[Bug] Heading token with mutiple end-of-line characters does not tokenized into Space token #3513
Description
Marked version: 14.1.2
Describe the bug
Heading Token (buggy)
Heading token with mutiple end-of-line characters does not tokenized into Space token:
// '# Heading\n\n'
{type:"heading", raw:"# heading\n\n", depth:1, text:"heading", tokens:[
{type:"text", raw:"heading", text:"heading"}
]}
But for other block-level tokens, two \n will be tokenized into a Space token:
BlockQuote Token
// '> hello\n\n'
{type:"blockquote", raw:"> hello", tokens:[
{type:"paragraph", raw:"hello", text:"hello", tokens:[
{type:"text", raw:"hello", text:"hello"}
]}
], text:"hello"}
{type:"space", raw:"\n\n"}
CodeBlock Token
// '```\nhello\n```\n\n'
{type:"code", raw:"```\nhello\n```", lang:"", text:"hello"}
{type:"space", raw:"\n\n"}
Paragraph Token
// 'paragraph here\n\n'
{type:"paragraph", raw:"paragraph here", text:"paragraph here", tokens:[
{type:"text", raw:"paragraph here", text:"paragraph here"}
]}
{type:"space", raw:"\n\n"}
List Token
// '* list item\n\n'
{type:"list", raw:"* list item", ordered:false, start:"", loose:false, items:[
{type:"list_item", raw:"* list item", task:false, checked:undefined, loose:false, text:"list item", tokens:[
{type:"text", raw:"list item", text:"list item", tokens:[
{type:"text", raw:"list item", text:"list item"}
]}
]}
]}
{type:"space", raw:"\n\n"}
Expected behavior
Why is the Heading token ending with two (or more) \n not tokenized into a space token? Is this expected?
Thank you for your response.
